XTLDIS—State of Crystal Oscillator at Reset.
This bit only enables the crystal oscillator. Its selection as system clock must be done man-
ually.
0 = Crystal oscillator is enabled during reset, resulting in longer reset timing
1 = Crystal oscillator is disabled during reset, resulting in shorter reset timing
All available Trim bit addresses and their functions are listed in
Table
Reserved—Altering this register may result in incorrect device operation.
Programming the XTLDIS bit to zero on 8-pin versions of this device prevents any fur-
ther communication via the debug pin. This is due to the fact that the XIN and DBG
functions are shared on pin 2 of this package. Do not program this bit to zero on 8-pin
devices unless no further debugging or Flash programming is required.
